Catalytic Converter for Honda CR-V (2017-2019) 2.4L Rear

Direct-Fit Rear Catalytic Converter for 2017-2019 Honda CR-V

What it Does: The rear catalytic converter assembly restores factory exhaust scavenging and federal emissions compliance on the 2017-2019 Honda CR-V to eliminate downstream P0420 trouble codes without custom exhaust fabrication.

The Stock Honda CR-V Substrate Breakdown

Factory catalytic converters on the 5th-generation RW1 and RW2 chassis endure severe thermal cycling and high-velocity exhaust pulses from the 2.4L Earth Dreams engine. Over time, the internal washcoat suffers thermal sintering, stripping the precious metal catalytic sites. Additionally, road debris impacts and thermal stress cause micro-fracturing across the stock ceramic core. This structural degradation leads to internal clogging, elevated exhaust backpressure, lost fuel economy, and sluggish mid-range acceleration.

The Engineering Solution

Engineered as a true bolt-on replacement, this assembly utilizes a durable, corrosion-resistant stainless steel outer shell paired with an ultra-efficient ceramic honeycomb substrate. The internal monolith is coated with a precise catalytic washcoat loading to effectively neutralize unburned hydrocarbons (HC) and carbon monoxide (CO). Precision-machined, heavy-duty flanges ensure an airtight seal against factory downstream pipes. The included mounting hardware and direct-fit configuration allow for immediate installation to restore proper exhaust dynamics and secondary O2 sensor readings.
